A. Yoga is a term for a physical, mental, and spiritual discipline, originating in India thousands of years ago.

Stone carvings of figures in yoga positions have been found by archeologists in sites dating back 5,000 years. The word yoga means "to join or yoke together," referring to bringing the mind and body together. Yoga started being practiced in the United States in the late 1800s, but did not become widely popular until the 1960s.

The three main elements of yoga are exercise, breathing, and meditation. There are hundreds of different schools of yoga, Hatha Yoga being one of the more well known.

It is called "hot yoga" when practiced in a heated room. Instructors set the temperature at 95 - 100 degrees Fahrenheit, or warmer, promoting maximal sweating and warm muscles. There are several styles of hot yoga.
